Smoke Detectors

Smoke and Carbon Monoxide Detectors

Home smoke detectors are an important safety feature. They help protect our families and our largest financial investment, our homes.  Over the past 20 years, there have been many important revisions to the national building codes related to smoke and carbon monoxide detectors. 

What are the benefit of updating your system?

  • Better coverage – The National Fire Protection Agency (NFPA 72) recommends the following MINIMAL requirements
    • One unit in each sleeping area, plus
    • One unit on each floor usually in the hallway or stairwell, plus
    • One unit in an unfinished basement or two units in a finished basement (one near the stairwell, the other near the mechanical equipment – HVAC and water heater)
  • Better communication – NFPA 72 recommends that all smoke and carbon monoxide units be interconnected so that if one sounds, the other units sound as well. Seconds count when there’s an emergency (fire or carbon monoxide). This feature gets notification to you and your family faster, regardless of where you are in your home.
  • Convenience – Some new units include long life batteries and don’t require battery changes or unit replacement for 10 years. Annual testing (see below) of the units by the homeowner is still advised.
  • Peace of mind – An updated system that’s in compliance with new codes and guidelines gives you peace of mind that you’re taking an important step to protect your family and your home.


Nothing lasts forever!  This is true for smoke & carbon monoxide detectors.

All smoke and carbon monoxide detectors have a maximum warranty of either 5, 7 or 10 years. Depending on the model, units need to be replaced on or before the end of the warranty periods.

THAT’S RIGHT.  THESE DETECTORS DON’T LAST FORWEVER!  Just because you press the test button and hear a beep, it doesn’t mean that the unit is in good working condition.  This only means that the battery is good.


Testing Your Current Smoke Detectors

If you’re not sure when your units were installed, look at the back of the unit.  As of the year 2000, all manufacturers are required to label their units with a manufacture date.   Any unit without a sticker should be replaced as soon as possible. Units with dates should be replaced following the manufacturer’s warranty guidelines.

To test a unit that’s still within the warranty, purchase a product called Smoke in a Can or similar type product.  Follow the instructions on the can.
